OLARRENCE L. LANDAS, OF TITUSVILLE, PENNSYLVANIA.

VIOLIN-BOW.

SPECIFICATION forming part of Letters Patent No. 413,069, dated October15, 1889.

Application filed April .26, 1889.

.To aZZ whom, it may concern.-

Be it known that I, CLARRENCE L. LANDAS, a citizen of the United States,residing at Titusville, in the county of Crawford and State ofPennsylvania, have invented a new and useful Bow for Violins and otherStringed Instruments, of which the following is a specification.

This invention has relation to bows for violins and other stringedinstruments, and has special reference to the frogs thereof.

Among the main objects in view are to provide a frog of such aconstruction as to facilitate the fill ng of the bow when occasionrequires, and this without the use of glue or other sticky substances,the means for accomplishin g the object being simple and inexpensive.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be particularly pointed out in theclaims.

Referring to the drawings, Figure 1 is a perspective of the frog of abow constructed in accordance with my invention. Fig. 2 is a verticallongitudinal section on an enlarged scale. Fig. 3 is a transversesection. Fig. 4 represents detail views of the novel parts.

Like numerals of reference indicate like parts in all the drawings.

' 1 represents the frog of a bow, which,with

the exception of certain features hereinafter mentioned, is similar tothose ordinarily used, the same being provided with a bottom recess 2,extending throughout its length, a metal tip 3,-an abutting wall 4-, anda removable slide 5. Vithin the recess 2 there is formed a secondshorter recess 6, which is of rectangular shape and fitted with acorrespondingly shaped bearing-plate 7. A vertical perforation 8 isformed in the frog, which extends throughout its height and communicates with the bearing-plate 7, which plate is provided with atransverse slot 9.

10 represents a binding-key; and the same consists of a head portion 11,adapted to fit the slot formed in the plate 7, and a reduced spindleportion 12, provided with screw threads. This key is of such a length asto extend about midway the vertical perfora- $erial No. 308,508. (Nomodel.)

threaded adjusting-shaft 16; and it further consists of a reducedportion 17, plain upon its outer surface, but provided with an internallyscrew-threaded bore 18, adapted for the reception of the reducedscrew-threaded portion of the key.

To fill a bow, by which is meant to provide the same with hair, it issimply necessary to rotate the binding-bolt so as to be moved upwardly,and thus the slot 19, of rectangular shape, formed in the head of thekey, is brought below the Jlane of the bearing-plate. It now remains tolnsert the ends of the hair. This having been done, by screwing thehinding-bolt downwardly the head of the key is drawn upwardly and thehair at each side thereof drawn snugly again st the walls of the recessformed in the bearing-plate. It now remains simply to regulate theadjustment of the filling thus mounted.

Having thus described my invention, I claim 1. In a frog for bows, amovably-mounted key provided with ahead having an opening, and a plateslotted for the reception of the head, in combination with means foroperating the key, substantially as specified.

2. In a frog for bows, a bearing-plate hav ing a slot, in combinationwith akey provided with a head having a slot and provided with a reducedspindle portion having screwthreads, and a binding-bolt mounted upon thekey and internally bored and screw threaded for the reception of thespindle, substantially as specified.

3. In a bow, a frog provided with a recess and a vertical perforation,in combination with a bearing plate mounted in the recess and a keymounted in a perforation and provided with a slotted head adapted to beprojected through an opening in the plate, and with a reducedscrerwthreaded spindle, and a binding-bolt provided with aninternallyscrew-threaded bore for the reception of the spindle, andwith. a transversely-apertured head for the reception of the adjustment-I nected therewith, and the binding-bolt 14, shaft, substantially asspecified. having a threaded connection with the key,
